Cyclone Philine on Sea

Cyclone/super cyclone can accelerate the cyclical loss of nesting beach, and decreasing hatchling success and hatchling emergence success could occur with greater frequency. However, susceptibility to storm-related threats may vary by species [such that species with lower nest-site fidelity (for example leatherback turtles Dermochelys coriacea,  would be less vulnerable than those with higher site fidelity (for example hawksbill turtles, Eretmochelys imbricata .Despite of the fact that some nesting beaches disappear between nesting years due to seasonal erosion and accretion processes, this natural phenomenon gets elicited by cyclone/storm resulting on complete loss of nesting area. Such conditions of behavioral flexibility may offer one of the most promising avenues for marine turtle’ s adaptation. Marine turtles are certainly able to colonize in new beaches near or far from the previous nesting beach. A shift and decrease in the area of nesting at Rushikulya rookery was recorded this year (2014) which was from Gokharkuda to Podumpeta. Prior this nesting was occurring from Purnabandha to Podumpeta in last few years [8]. Despite of this, there are no studies to our knowledge that examine the impact of beach fortification on regional turtle nesting populations. The objective of this study was to look at the geomorphologic changes in Rushikulya sea turtle rookery and impact on sea turtles after super cyclone.
